Zorluk: KolayPhysiological Effects of Alcohol on Driving Performance

Consuming alcohol slows a driver's central nervous system response, increasing reaction time even when performing simple motor actions such as stepping on the brake pedal.

Cevap: Cevap

Cevap

The statement is true because alcohol depresses central nervous system functions, delaying motor transmission and increasing brake reaction time regardless of how simple or automatic the physical movement may seem.
The statement is correct because alcohol depresses central nervous system activity. This biological slowing directly retards neural messaging between the brain and body muscles, resulting in measurably longer reaction times for simple motor actions like braking.

Adım Adım Çözüm

1
Identify the primary physiological impact of alcohol on the central nervous system.
Alcohol acts as a central nervous system depressant, slowing down nerve impulse conduction and brain processing speed.
Understanding the fundamental biological effect of alcohol is necessary to evaluate physical response times.
2
Relate central nervous system depression to physical driving actions.
Delayed nerve signals increase the time required for a driver to perceive a hazard and physically move their foot to the brake pedal.
Drivers must synthesize perception and physical response, both of which are slowed by alcohol impairment.
